Detail

According to investigations of ABS population statistics for the surrounding region, combined with fresh street addresses verified by AreaSearch since the Census, the suburb of Mount Martha has a residency count estimated at 20,161 by May 2026. This represents an addition of 315 residents (1.6%) compared to the 2021 Census, which documented 19,846 individuals. This shift is derived from the resident population of 20,161, calculated by AreaSearch using the most recent ERP statistics from the ABS (June 2025) and a further 102 verified new addresses since the Census. Such a population size translates to a density of 667 persons per square kilometer, indicating substantial personal space and capacity for prospective expansion.

The 1.6% rise since the census puts the suburb of Mount Martha within 0.4 percentage points of the SA3 region (2.0%), showing healthy local growth characteristics.

AreaSearch employs projections from the ABS and Geoscience Australia for individual SA2 zones, which were published in 2024 using 2022 as a base. For SA2 zones lacking this coverage, AreaSearch uses VIC State Government regional and LGA projections from 2023, modifying them with a weighted aggregation technique to translate LGA population growth to SA2 dimensions. The growth patterns by age from these aggregations are also projected forward for the years 2032 to 2041. Looking at future demographic trends, the suburb of Mount Martha is projected to experience population growth above the national median, with expectations to grow by 3,084 residents by 2041 based on compiled SA2 projections, representing an overall increase of 15.3% across the 16 years.

Residential SupplyHousing Development & Building Approvals in Mount Martha

Table Chart PROFILE FAQ

339 new dwellings have been approved in Mount Martha over the past five years, an average of 67 a year. That is 3.4 approvals per 1,000 residents. Of the 69 dwellings approved in the latest reporting year, 72% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 49, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.

Detail

According to building approval figures from the ABS compiled by AreaSearch for local areas, the suburb of Mount Martha has averaged approximately 67 residential approvals annually, leading to an estimated 339 dwellings over the prior 5 financial years. In FY-26 to date, 45 approvals have been logged. Because construction added only 0.3 new residents per dwelling annually over the last 5 financial years (from FY-21 to FY-25), the incoming housing volume is keeping pace with or outstripping local demand, providing plentiful options for purchasers and establishing capacity for growth beyond current projections.

Meanwhile, newly built properties carry an average construction value of $1,722,000, showing that developers are focused on the upscale market with high-end designs. Furthermore, commercial approvals worth $10.1 million have been logged this financial year, showing ongoing commercial spending. Compared with Greater Melbourne, building approvals per resident in the suburb of Mount Martha run at approximately 65% of the rate, positioning it in the 50th percentile among all locations analyzed across the country. This sits below the national benchmark, reflecting the established state of the local area and pointing to prospective planning constraints. Upcoming construction consists of 72.0% separate houses and 28.0% multi-unit developments or townhouses, which maintains the low density character of the area through a focus on detached homes that appeal to buyers wanting space. Recording roughly 331 individuals per approved dwelling, the suburb of Mount Martha demonstrates the traits of a low-density neighborhood. Demographic projections indicate the suburb of Mount Martha will add 3,084 citizens by 2041 (compared to the most recent quarterly calculation from AreaSearch). If building rates do not increase, housing supply could fall behind demographic growth, which will likely heighten competition among buyers and support price increases.

Application search is not available in Victoria. AreaSearch holds 309 applications for Mount Martha, but they are a record of past activity rather than a current register. Victoria has no state-wide planning portal and its council coverage is uneven, so we have switched the search off here rather than return partial answers. We are currently investigating a solution. No credits are charged for Victorian applications, and building approvals from the ABS and the major projects we track are unaffected.

How the numbers are built

Population

The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 102 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (19,846 at the 2021 Census → 20,161 now). Annual growth rates are compound (CAGR), not simple averages.

Age profile

Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".

Property sales

Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.

Rents

Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.

Development & infrastructure

Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.

Employment & income

Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.

Education, transport & amenities

School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.

Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.

Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL21803). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Mount Martha suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Mount Martha page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Mount Martha data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (May 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
